Description
Zhe Wu and co-authors built a layered material in 2026 that swallows long-wave infrared light for one polarization far more than the other. Artificial absorbers of this kind are thin, light, and efficient, and ones that also sort light by polarization could replace bulkier optical parts. The devices work through surface plasmon resonances at the metal boundary.
Their stack pairs copper, silicon, and titanium in three layers, and reached a polarization extinction ratio reported as fourteen. A richer four-part surface pattern then held an average ratio near nine across the eight to fourteen micrometer band, reaching toward very long wavelengths. Readers get a design study in selective darkness: a film that drinks one polarization of heat glow and mostly refuses the other, for sensors and thermal cameras.
